BOOK-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 442,295, dated December 9 1890.

Application filed April 4, 1890- Serial No.346,624. (N0 model.)

To all whom it may concern.-

Be it known that 1, CHARLES SEYBOLD, a citizen of the United States, residingat Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Book -Trimming Machines, of which the following is a specification, reference being had to the accompanying drawings, formingapart thereof, in which similar letters of reference refer to correspon ding parts of the machine throughout.

The primary object of my invention 18 to provide a machine for trimming bundles of paper into book form, the said machine being so constructed as to clamp the bundle to be trimmed in proper position and afterward to automatically trim or out each side of the bundle consecutively without stopping the machine, the latter being. so constructed as that it will stop automatically'after having made the fourth or last cut, as will more fully hereinafter appear.

' In the accompanying drawings, Figure 1 is a front elevation of a machine embodying the features of my invention, the length of the machine as shown in comparison to the height thereof being about one-third longer than what the machine is actually built. Fig. 2 is a horizontal section taken on the dotted line 2 2 of Fig. 1, showing the top portion of the bed plate, clamptable, and operating mechanism. Fig. 3 is an end elevation taken at left hand in Fig. 1, showing the preferred form of mechanism for causing'the knife-carriage to automatically move back and forth onthe bed-plate, the upper portion of said knife-carriage and clamping mechanism being broken away. Fig. dis a vertical section taken on the dotted line 4.- at of Fig. 1, looking toward the right hand in said figure, showing thepreferred means for securing the clampscrew and its connecting parts in proper position, and also the preferred means for automatically rotating the clamp-table a partial rotation at certain determinate intervals. Fig. 5 is an end elevation of the machine shown at right hand in Fig. 1, the dotted lines showing the position of the knife-carriage when the latter has traveled forward in position for the knife to trim one side the bundle of papers held to place in the clamp. Fig. 6 is a section taken on the dotted line 6 6 of Fig. 4, being a top view of the clutch mechanisnl for imparting a rotary motion to the clamp-screw in either direction and of the mechanism for automatically rotating the clamp-table a partial rotation at certain determinate intervals. Fig. 7 is a side elevation of a part of the lever for automatically stopping the machine and its connecting parts, the dotted lines showing said lever ele vated, in which position the machine does not operate. Fig.8 is a vertical section taken through the knife-bed, knife, and the vertical cross-plate of the knife-carriage, showing one of the rollers which support the knife-bed in position in the inclined groove in the crossplate. a

My improved machine for trimming bundles of paper into book form is preferably constructed as follows:

The operating mechanism is supported and journaled in suitable frame-work Aand brackets attached thereto, said frame-Work being covered with a suitable bed-plate A, attached thereto, the rear extensions G6 of the b'edplate being supported by the brackets Afi'as shown. I: r

The mechanism for clamping the bundle of paper in position to be cut is preferably con structed as follows: The clamp-screw B is held in position by means of a washer 19, (see Fig. 4,) interposed in a circular recess in the top of sleeve B, directly beneath the clamprtable C, as shown, the said sleeve B having an enlarged circular head B resting in acircular count-ersunk portion of the bed-plate A, the table 0 being connected to said enlarged head of the sleeve, as shown in Fig. 4. To' the lower end of screw-rod B is securedthe miter: wheel B which latter engages with the corresponding miter-wheels B B placed on the main shaft B and held to place by means of the set-collars Z2, as shown in Figs. 1 and 6. To the clam p-table O are connected the vertical guides C C, between which thescrewclamp 0 travels up and down on the screwrod as the latter is rotated in either direction; To the clamp O is bolted or otherwisesuit ably secured the pattern or form plates 0 the latter being made of varying sizes. to conform to the size of book desired to be imm d- To he m in ha B and et en the miter-wheels B is secured the frictionwith the tight pulley, and-the pin cl is drawn out of the opening f in lever F, permitting the outer end of said lever F to drop down in the bracket f in which position the pin cl is held against the outer face of lever F just above the opening f ,as shown by dottedline in Fig. '7, by means of the spring (1'. The clutch is held in position in contact with the tight pulley by reason of the pin d bearing against the face of lever F, which causes the clutch-pinion D to impart motion to gear E, and as gear E is rotated the pinion E connected thereto rotates and with it the gear The pinion E being one-fourth the diameter of gear E it will take four revolutions of said pinion to accomplish one revolution of said gear, and so soon as the pin 6 on gear E comes in contact with the inclined face of lug f on lever F the outer end of said leveris elevated, as shown by dotted lines in Fig. 7, in which position the pin (1 on lever B is drawninto the opening f by means of spring (1', which operation draws the clutch away from the tight pulley and stops the operation of the machine. 7

It will be seen that the machine is stopped automatically at every fourth revolution, the number of revolutions to be given the auxiliary shaft before stopping the machine being governed by the size or number of cogs on pinion E, which .may be varied, if desired. The object of this arrangement for automati cally stopping the machine at each fourth revolution of the auxiliary shaft is to permit of the trimmed bundles being removed, each revolution of the auxiliary shaft trimming one. side of the bundle, as will more fully herein after appear.

The knife G is secured to the knife-bed G by means of bolts g, passed through the knife and resting in a countersink in such a manner as that the head of each bolt will come flush with the outer face of the knife, said bolts passing through the elongated openings a in the lower portion of the knife-bed G, as shown in Fig. 8. The knife is adjusted vertically' on its bed by means of the set-bolts g, after which the nuts on the bolts g are tightened. Between the outer upward extension 9 of .the knife-bed is secured the rod G around which is secured a stiff spiral spring 9 interposed between the lug g and lug g the latter being loosely connected to said rod, the said lug 9 having the roller g pivotally connected to a stud thereon, as shown in Fig. 1. This roller g has the side circumferential flanges which engage the outer and inner face. of guide G against which said roller impinges and rotates as the knife-bed is raised or lowered. The knife-bed is held in place between the vertical guide-plates G3 and the rear vertical plate G of the carriage in an elevated position by means of the spring g which is compressed around the rod G between the stationary lug g and the sliding lug g connected to roller g". To the rear of the bed-plate is connected suitable lugs on which the rol'lersg rotate, the latter rotating against the lower face of the elongated inclined grooves g in the rear plate G as shown in Fig. 8 and by dotted lines in Fig. 1. When the knife-bed is forced downward, the rollers 9 travel down the face of said inclined grooves, said knife-bed being elevated again by the tension of spring g against the lug 9 the latter traveling up with its roller g rotatiing against the guide-plate G The knife carriage is made up of the vertical end plates G, guide-plates G rear cross-plate G and rearward extensions G. This carriage is upheld and travels upon the rollers G which latter rotate upon suitable spindles connected Having described the preferredconstruction of the carriage, knife-bed, and knife and their connecting parts, I will now describe the preferred means, as shown, for operating the knife-bed and its knife, which is as follows:

Between the extensions H, cast with the end frame A, is pivoted the lever E to the lower end of which is connected the roller 6, which latter rotates and bears against the two inclined faces of the cam E in the manner aforedescribed. The upper portion of this lever E above its pivotal point is bifurcated, as shown in Fig. 5, a suitable shaft H being connected to the top portions of said bifurcations, as shown, on which shaft is placed the flanged roller H This roller rests and rotates against the vertical gage H the latter being connected to oneend of the knife-bed by means of the set-screws h, which operate IIO in extensions of said gage against said knifebed, as shown in Figs. 1 and 5. The flanged roller H is kept in contact with the gage at all times,-and moves back and forth onthe shaft as the carriage travels forward or back: ward. may be dispensed with, in which event the roller will operate against the vertical face'of the knife-bed; but it is preferred to employ said gage to assist in adjusting thedownstroke of the knife, The operation of this portion of the machine is as follows: The revolution of cam Ef 'causes the roller 3 to travel outward over its inclined face e, thus forcing the lower end portion of lever E outward and its upper bifurcated portion inward and downward, and with it the knife-bed and its knife, the roller H traveling down over thev face of gage H. So soon as the roller 6 ;on'

lever E has passed the outermost point on,

the face 6' of the cam the pressure on the knifebed is released,and the latter, with its knife, is elevated through the tension of spring If desired,'this gage and set-screws tion, with the roller 6, is forced inward, said roller traveling back on the inclined face e of the cam, as shown in Fig. 1,in which position it. is in readiness to begin another out.

Itis desired that the knife be not elevated I higher than the thickness of paper after behereinafter appear.

ing clamped in position, for the reason that the knife must strike against the form-plate O as thecarriage is traveling forward, as will justing th e height to which said knife maybe elevated, I have provided the set-screw H which operates in the bracket 71 connected to the projections H, as shown in Fig. 1, the outer end of said screw bearing against the lever E below its pivotal point. Turning the screw in one direction forces the upper portion of the lever inward and the knife is low- 'ered, above which point it can in no case be elevated except by turning the screw in the opposite direction, which will permit the lower portion of the lever to move inward, and the knife will be correspondingly elevated.

The depth of stroke to be given the knife is regulated principally by means of the gage of the set-screws h.

H, which is wedge-shaped on its inner face and rests against the inclined outer face of the knife-bed, as shown, said gage being regulated up or down on said knife-bed by means To lower the cut the gage is elevated, and to elevate the cut the gageis lowered.

Having described the construction of the carriage and the construction and operation of the knife-bed and knife on said carriage, I will now describe the preferable, construction of mechanism shown for automatically operating said carriage and its knife up to and away from the form-plate clamped on the bundles of paper at certain determinate intervals. This mechanism for thus causing the carriage to automatically travel back and forth on the rollers G the latter resting on the bed-plate A and its rearward extensions, is fully shown in Figs. 1, 2, and 3, and is as follows: "To the auxiliary shaft E, outside the frame, is keyed the disk K and toothed segment K, said disk being provided with the beveled toothed portion 1 for about one-quarter of its inner circumference, said teeth on the disk meshing with the beveled pinion L at one side thereof, which imparts motion in one direction to said pinion. The segment K in its T rotation imparts motion to the pinion L in a direction opposite to that imparted by the toothed portion of the disk, said segment being so-located as that it will act shortly after the said toothed portion of the disk shall have passed said pinion. The pinion L is keyed to'the shaft L, to which latter is also keyed the stop-lug L which latter has a flatv faceto impinge againstthe inner face of the outer bearing-faces Z on the disk K, said bear- For the purpose of ad-' ing-faces being so located asthat the fiat face of stop-lug L will bear. against the bearingfaces 1*, when the teeth of said segment. and disk are not in contact with said pinion, the object being to retain said pinion in proper position to mesh with the segment and toothed portion of the disk in their rotation. To the shaft L is connected the two. caps L by means of a'feather-and-groove connection, to p I admit of a vertical movement to said caps, between which the pinion L is loosely connected to said shaft, but connected therewith by the tension of aspiring L interposed between the top cap L and nut 1 suitable fric- V tion-washers being interposed bet-ween said caps and pinion. To the outer edge of the knife-carriage. is connected the horizontal toothed rack M,in which the pinion L meshes in its rotation in either direction. The operation of this feature of my invention is as follows: Motion being imparted to the auxiliary shaft E, the disk K and segment K are rotated in the same direction on opposite sides of the pinion L, which causes an inter- KOO enough to hold said pinion in position and to operate the carriagev back and forth; but so soon as the knife on the carriage moves up and strikes the'form-plate C on the clamp the forward movement of the carriage is stopped and the pinion L ceases to rotate, the caps L? rotating on said pinion until the teeth Zon the disk have passed the pinion L. So soon as the knife strikes the form-plate it is made to descend with a shearing cut in the manner aforedescribed, and after having made its cut the carriage and knife are carried back by means of the toothed segment ,K'. The object of having this pinion L loosely connected to its shaft and held in position by friction is to accommodate varying sizes and p configurations of form-plates which are used to determine the size of book or bundle to be trimmed. X

I will now describe the preferable construe: tion of the mechanism shown for automatically imparting a partial revolutionof the table on which the bundles of paper are clamped after the carriage and its knife have receded from the form plate, as aforede-. scribed, which construction is as follows:

T o the auxiliary shaft E between the end 7 frames is keyed thevertical disk N, having a horizontal lug 71 castto its inner face, which lug, as the disk is being rotated, engages with" one of the vertical lugs 11', cast'to the bottom portion of the horizontal plate N, as'shown in Figs. 4 and 6. The plate N is keyed to the vertical shaft N to which latter is also keyed the gear 0, which meshes with a similar gearconnected to the sleeve B, (see Fig. 4,) the enlarged head B of said sleeve being connected to the table C, on which the bundles of paper are clamped. A portion of the outer clrcumferential face of disk N near the lug n is cut away, as shown at 92 Fig. Lin order to permit one corner of the horizontal plate N to give a quarter-turn over said disk at its cut-away portion when the lug n on the disk comes in contact with one of the lugs n on the plate. The inner face of said disk impinges against one face of the plate at all times, except at its cut-away portion, thus securely retaining said plate and the table in position for the knife to act.

The operation of this feature of my invention for automatically imparting a partial rotation to the clamp-table at certain determinate intervals is as follows: A rotary motion bein g imparted to the auxiliary shaft, the vertical disk N is rotated, as indicated in Fig. 4.

- the lug n coming in contact with one of the vertical lugs 72 on the horizontal plate N, and so soon as the two lugs come in contact the plate U is given a quarter-turn, the corner of said plate passing. over the disk at its cut-away portion, as indicated by dotted lines in Fig. 6. Each successive revolution of the disk gives a quarter-turn to the plate, which motion is imparted to the table 0 through the medium of shaft N gears O O, and sleeve B, to which latter the gear 0 and table 0 are connected, as shown in Fig. 4.

Having described the operation of each operative part of the machine in con nection with its preferable construction, I will now briefly describe the operation of the machine as a whole.

The bundle or bundles of paper to be trimmed are placed on the table C at either i side the guides C, after which the form-plate C attached to the clamp 0 is made to descend on the screw-rod by putting pressure on one side the foot-treadle B, the pressure being applied until the paper is sufliciently clamped, when the pressure is removed, causing the clutch to disengage with one of the miter-wheels 13*, as aforedescribed. Having clamped the bundles of paper in position, as shown in Fig. 5, the operator grasps the lever D giving it a pull inward, which starts the machine in motion. The pin (1, bearing against the face of lever F, serves to retain the clutch in contact with the tight pulley until automatically released, as will presently appear. So soon as motion is imparted to the auxiliary shaft E the teeth Z on disk K will cause the knife-carriage to travel forward on the bed-plate, in the manner aforedescribed,

Y until the knife G strikes the inner face of the form-plate 0 as shown by dotted lines in Fig. 5. So soon as the face of the knife strikes the form-plate the motion of the carriage is stopped in the manner described, the pinion L being held to place by friction between the caps L The cam E is so adjusted with refthe knife-bed G, lever E and cam-E in the manner aforedescribed, accurately trimming one side of the paper,and so soon as the knife has made its out the carriage begins to travel backward through the medium of segment K, and the knife-bed and knife are gradually elevated again in the manner described. The carriage and its knife having traveled up to the form -.plate, made one cut, and receded again, it is necessary that the clamptable, paper, and form-plate be given a quarter-turn in order to present a new face to the knife. This is accomplished automatically by adjusting the disk N and plate Ninsuch a position with reference to the segment 'K and cam E as that after said segment shall have caused the carriage to travel back and after the knife has been elevated in the manner aforedescribed the lug n on the disk N will come in contact with one of the lugs 11 on plate N, which will cause the table to be given a quarter-turn, as set forth. The inner face of the disk N bearing against the side of the plate N, except at its cut-away portion, will securely retain said table in a fixed position until the knife has again made its out and receded, as described.

It will be seen that it takes but one revolution of the auxiliary shaft to cause the knife-carriage to carry the knife up to the form-plate, cut one side thebundles of paper, elevate and carry the knife again, and give the clamp-table a quarter-turn, presenting a new face to be trimmed. Each successive revolution of the auxiliary shaft automatically carries the knife forward, cuts one side the bundle, elevates and carries the knife back away from the form-plate, and gives the latter and the clamp-table one quarterturn, until atthecompletion of the fourth revolution of said shaft, after the four sides of the bundles have been trimmed, the machine is automatically stopped by means of the lug e on gear E coming in contact with the projection f on leverF, (see Fig. 7,) which causes the outer end of said lever to be elevated,

which will cause the pin (Z on lever D to drop into the opening f in said lever F by reasonof the tension of spring (1, which operation will Withdraw the clutch from the tight pul ley, stopping the machine.

It is apparent that my improved machine for trimming books may be advantageously used to trim circulars, posters, and various other articles besides books and may be adjusted, if so desired, to trim articles having more than four faces by simply changing the gear E or the pinion E so that it will require more than four revolutions of the auxiliary shaft to automatically stop the machine.

The advantages of my improved machine for trimming books will be apparent when the time saved is taken into consideration. The features of automatically carrying the knife back and forth, rotating the clamp-table, and stopping the machine all at certain deter-. minate intervals are very valuable ones when combined in a book-trimmer such as I have shown and described.

\Vhile the mechanism shown for accomplishing the various operations enumerated automatically is the preferred form, any suitable operative mechanism may be employed for automatically carrying the knife up to and away from the form-plate, rotating the clamp-table a partial rotation, operating the knife, and stopping the machine all at certain determinate intervals. If desired, one or more of said features of my invention may be used in connection with book-trimmers ditt'erin g in construction from that herein specifically set forth.
